The motor air supply method mainly utilizes the aerodynamic effects in the suction tude, realizes the air inlet of motor.Aerodynamic effects can be considered the air-flow inertia effect and the common result of stream pressure fluctuation effect.
In the air-flow inertia effect, generally be that the effect of inertia of the interior flow at high speed gas of suction tude when utilizing intake stroke improves charging efficiency.At the engine charge stroke in earlier stage, because the suction effect of descent of piston produces negative pressure in the cylinder, fresh air enters from suction tude.In the piston arrives aspirating stroke after bottom dead center, because gas swiftly flowing inertia in suction tude still can continue as cylinder charge a period of time.But for making full use of the air-flow inertia effect, can only increase the length of suction tude, be limited to actual use condition, the length increase of suction tude can cause complex structure, and difficulty is installed.
The stream pressure fluctuation effect is meant each cylinder cycle, intermittent air inlet and the stream pressure fluctuation that causes producing in the suction tude certain amplitude.The air-flow of suction tude can back and forth fluctuate along suction tude, and the propagation back and forth that goes round and begins again in suction tude is low when high when causing the pressure of cylinder ingress.If the shape of suction tude, length and diameter are more suitable, help pressure wave reflection and resonance, and barotropic wave is overlapped with next circulation intake process, and air inlet pressure is at the end raise, and reach the purpose that improves charging efficiency.
For utilizing the stream pressure fluctuation effect, most of motors all are provided with a power cavity or are provided with a resonant cavity that communicates with suction tude on the next door of suction tude in suction tude, and the resonance that is beneficial to suction tude internal pressure ripple improves aeration quantity.In addition valve is set in suction tude, controls the air inlet cross-section area of gas-entered passageway, and then increase the efficient of air inlet.
Power cavity that increases in the existing technology or resonant cavity all are arranged in suction tude, and be far away from cylinder distance, do not have stored-gas and replenish the effect of air inlet to cylinder.Power cavity or resonant cavity are arranged in the suction tude in addition, and because the quick running of motor, can in intake manifold, produce higher pressure reduction, what so high pressure difference was brought is exactly to impact and pulsation, by the gas Sasser that produces, traditional air inlet method can not filter out Sasser, causes oscillating wave to influence very much air inlet stability.Can not control the air inlet cross-section area in real time and change with working conditions change and valve is set in suction tude, it is not obvious to cause efficient to improve.

Below in conjunction with accompanying drawing preferred implementation of the present invention is elaborated.
As shown in Figure 1, engine aspirating system provided by the invention comprises intake manifold 1, this intake manifold 1 comprises gas inlet 2 and at least one gas outlet 3, wherein, this gas handling system also comprises at least one Buffer Pool 6, Buffer Pool 6 is communicated with intake manifold 1, and the distance of the interface 4 that is communicated with intake manifold 1 less than Buffer Pool 6 of the distance of the interface 4 that is communicated with intake manifold 1 of Buffer Pool 6 and gas outlet 3 and gas inlet 2.
The cylinder of motor can be one, and at this moment, the gas outlet 3 of the intake manifold 1 that links to each other with the cylinder of motor is one, and Buffer Pool 6 also is one.
In most cases, the cylinder of motor is a plurality of, and therefore, under the preferable case, the gas outlet 3 of the intake manifold 1 that links to each other with the cylinder of motor is for a plurality of, and in this case, Buffer Pool 6 can be one, also can be a plurality of.Under the preferable case, as shown in Figure 1, gas outlet 3 is a plurality of, and Buffer Pool is 6 to be one, and Buffer Pool 6 is communicated with intake manifold 1 by a plurality of interfaces 4.Each interface 4 is between gas inlet 2 and gas outlet 3.Buffer Pool 6 is communicated with by a plurality of interfaces 4 with intake manifold 1, can guarantee that Buffer Pool 6 can be a plurality of cylinder air feed, also can make the gas flow of minimizing be replenished rapidly.

According to embodiment preferred of the present invention, described make-up gas 8 is stored in the foregoing Buffer Pool 6.The volume of Buffer Pool 6 is big more, and it is big more that intake efficiency improves, the buffer function that rises also obvious more.But because the restriction of real space, a cylinder volume ratio of Buffer Pool 6 volumes and motor is 0.5-1.5, is preferably 0.9-1.1 and can guarantees to have in the Buffer Pool 6 make-up gas 8 of q.s to enter like this.
According to air inlet method provided by the invention another preferred embodiment, between make-up gas 8 and cylinder inlet 9, valve 5 is arranged, valve 5 is with consistent described in the gas handling system of front.
According to the further preferred implementation of air inlet method provided by the invention, this method comprises that also control step and engine air throttle detect step.
As shown in Figure 6, described engine air throttle detects the position that step is used for the detection of engine closure, and the position of detected engine air throttle is converted into the electrical signal of the position of expression engine air throttle, and this electrical signal is sent to control step.
Control step is used for this electrical signal is converted into the opening value Δ S of expression throttle opening, and according to the opening value D of opening value Δ S control valve 5.
Throttle opening is big more, and the desired gas amount is many more, the corresponding increase of the aperture of valve 5, so that the air of q.s enters motor, opening value Δ S and opening value D are proportional relation.For satisfying above-mentioned requirements, the ratio of opening value Δ S and opening value D is preferably 0.5-1.5.0.9-1.1 more preferably.
Under the preferable case, detect the maximum value of electrical signal of the position of the expression engine air throttle that transforms in the step and represent that opening value Δ S is zero, the opening value Δ S that minimum value is represented is 90 degree, and along with the reducing of value of electrical signals, opening value Δ S increases.
According to a specific embodiment of the present invention, the detection step is converted into voltage signal with the position of engine air throttle, when the closure complete shut-down, detect the voltage signal maximum that step transmits, during WOT, voltage signal minimum, and the corresponding less opening value Δ S of bigger voltage signal.For example, the maximum value that can set this voltage signal is 5 volts, and minimum value is 0 volt, and voltage signal whenever reduces 0.5 volt, and opening value Δ S increases by 10 degree.
